WILLIAM ROBERT BELL, OF NEV YORK, N. Y.

MOTOR.

SPECIFICATION forming part of Letters Patent No. 402,713, dated May 1889.

Application iiled February 27, 1889. Serial No. 301,330. (No model.)

To all whom it may concern.-

Be it known thatI, WILLIAM ROBERT BELL, of the city, county, and State of New York, have invented a new and Improved Motor, of which the following is a full, clear, and exact description.

The obj ect of my invention is to provide an inexpensive and reliable motor for light-running machines, such as sewing-machines; and to the end named the invention consists, essentially, of a sleeve or shaft that is to be driven, said shaft or sleeve being formed with recesses, pawls mounted in said recesses, rings formed with internal ratchets, said ratchets being arranged so that they will be engaged by the pawls, and bands connected to the rings and to a frame, all as will be hereinafter more fully explained, and speeiiically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this speciiication, in which similar figures and letters of reference indicate correspondin parts in all the views.

Figure 1 is a side View of my improved motor. Fig. 2 is an enlarged sectional View taken on line 2 2of Fig. 1. Fig. 3 is a sectional View taken on line 3 3 of Fig. 2. Fig. 4 is a view on line 4 4 of Fig. 2, and Fig. 5 is a detail view of one of the tightening devices.

In the drawings, 10 represents a balancewheel, which also ser Jes as a pulley, if desired, the driving-belt being in such oase placed-in the groove e, formed in the rim 11. The'wheel 10 is mounted on a stud, 12, and held from displacement by a collar, 13, and a washer, 14, that is held to the stud by a screw, n, the wheel-hub being formed with an extending sleeve, 15, which abuts against the washer 14.

The sleeve 15 is recessed at ff', and in these recesses there are mounted pawls 16 and 16, such pawls being supported by a pin, 17, arranged as best shown in Fig. 2.

Upon the sleeve 15, I mount rings 1S, 19,20, 21, and 22, the rings 18, 20, and 22 serving as spacing-rings and as supports for afranie, 30, while the rings 19 'and 21 are the drivingrings and are formed with internal ratchets t' t', that are engaged, respectively, by the connection with the pawls.

The frame 30 carries four bands or cords, a, b, c, and d, the cords or bands a b being passed about the ring 21 in opposite directions to engage a pin, 0, the ends of the bands or cords being looped to provide for the passage of the pin, while the bands o and d are correspondingly connected to the ring 19, the connection, however, being upon the opposite side of the ring. The bands a and d and c and b extend about their rings in the saine direction. It will be noticed that the pawls 16 and 16 point in the same direction.

In order that the frame 30 maybe reciprocated, I connect it with a treadle, 31, as shown in Fig. 1.

If the treadle be moved as indicated by the arrow, the frame 30 will be drawn downward and the cord or band b will draw its ring 21 in the direction of the arrow shown in Fig. 3, and the ring so moving would advance the wheel 10, inasmuch as the pawl 16 would be engaged by the ratchet t. As the frame 30 is moved downward, as just described, the cord d would draw on its ring 19 and such ring would be moved, as indicated by the ar row marked ne in Fig. 4; but when the frame 30 is moved upward the cord cwould draw on the ring 19 and the ring would be carried in the direction of lthe arrowr marked y.

From the above description it will be seen that when the frame moves downward the ring 21 drivesthe wheel 10, while the ring 19 slips over its pawl, and that when the frame moves upward the ring 19 drives the wheel 10 and the ring 21 slips, and itwill also be seen that an exceedingly slight movement of the frame will act to drive the wheel.

In practice I prefer that the bands a, Z2, c, and d should be made of steel, and in such case I connect the bands at one end of the frame to hooks, as p, and at the other end of the frame to clamps r, having threaded shanks pawls 1G and 1G, springs 7e being arranged in s, that are engaged by winged nuts t, this arrangement being preferred in order that all undue slack may be taken up.

Although I have described my motor as being arranged in connection with a sleeve forming a portion of the drivingwheel, I desire it IOO to be distinctly understood that the motor might be arranged in connection With ashaft.

It will be noticed that the rings 1S, 20, and 22 serve as supports for the frame 30, such frame being guided at one side by the Wheelhub and at the other by the Washer 14.

Having thus described iny invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a motor, the combination, With adriven member provided With. paWls, of rings formed with internal ratchets that are engaged by the pawls, bands passed about the rings in opposite directions, and a frame to Which the bands are connected, as and for the purpose stated.

2. In a motor, the combination, with a driven member provided with pawls, of rings formed with internal ratchcts that are engaged by the pawls, bands passed about the rings in opposite directions, a frame to which the ban ds are connected, a treadle, and a connection between the treadle and the frame, substantially as described.

3. In a motor, the combination, with a driven member provided with pawls, of a ring, 19, formed with an internal ratchet that is engaged by one of the paWls, bands connected to the ring and passing in opposite direction about said ring, a frame to which the bands are connected, a ring, 21, also formed With an internal ratchet that is engaged by the other pawl, bands which pass in opposite directions about and are connected to the ring 21, the point of connection being opposite that of the ring 19, connections between the bands and the traine, and means for reciprocating the frame, as and for the purpose stated.
